ICE-GBEAM-DISPENSING MACHINE.

Patented Nov. 9, i920.

Application filed May 3, 1920. Serial No. 378,714.

To all whom it may concern:

Be it known that we, RICHARD H. GARM- NER and HARRY (J. STACEY, citizens of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota,have invented certain new and useful Improvements in lce-Creain-Dispensing Machines, of which the following is a s ecification.

m invention relates to ice cream dispensing machines and-the object is to provide means for extracting icecreain from. the ordinary cream can or containers and deliver the same in convenient small equal quantities for filling dishes or pastry cones.

The invention is clearly illustrated in the.

accompanying drawings, in which;

Figure 1 is a side elevation of the coniplete machine shownas secured in place on an ice crearn can.

Fig. 2 is a detail view of the plunger, showing a portion of thecan and other parts of ,the machine in section.

I Fig. dis a detail sectional view substantially on the line 3-3 in Fig. 1.

Fig. l is a detail top viewof a portion of the casing 7, with the cover 8 removed.

F ig. 5 is an enlarged detailsectional view on the line 5-5 in Fig. i.

Fig. 6 is an enlarged detail sectional view on the line 6-6 in F ig. 1.

Referring to the drawings by reference numerals 9 designates an ordinary cylindrical ice cream container having a head 10 about the top thereof. About the can 9 is secured with a suitable hand clamp ii a clamping ring 12, which, at opposite sides, has two uprights 13 and i l on the top of which is secured a casing l having a cover 8 bolted thereto. A. piston or plunger 15 is positioned and constructed to slide vertically up and down in the can t and is provided with a piston ring 16 which insures a tight joint between the can and the piston. The plunger is further provided with a plunger rod 1'? having square threads 18 on its upper portion, said rod being; slidably supported in the casing 7 and cover 8. A transverse horizontal drive shaft 19 is journaled in a casting 26., which is secured on the rod 17, and on which is positioned. electric motor 21 having a pinion gear 23 is slidably keyed on so that it may be meshed with and driven bythe pinion 22 when so i desired. The aha 19 is provided with a hand crank 24 at one-end and at the other end is provided. with a bevel pinion 25 which meshes with a bevel gear 26 which is slidably keyed to travel over the length of a vertical shaft 27. A journal member 28 is also slidable on the shaft 27 and serves to secure the pinion 25 and gear 26 in rigid relation. The lower end of the shaft 27 is centered to rotate on a bracket 29 secured to the upright 13, and has its upper end journaled in the casing]. it is provided at its upper end with a bevel pinion 30 adapted to mesh with a second bevel pinion 31, both within I the casing. A shaft 32,-to one end of which is secured said pinion 31, is journaled at 33 and is provided with a worm screw 3% which meshes with and drives a floating worm gear 35. The gear 35 is held in place between the casing 7 and cover 8 (see Fin". 5), and is provided with internal threads which mesh with the teeth 18 on the shaft 1?.

' The plunger 15 is provided with a single aperture 36 (see 3) directly above which is constructed 'a delivering elevator which consists of a suitable casing 37 in which is mounted two pulleys 38 and 39, the latter being secured on the shaft 19. A belt or chain 40 is stretched over said pulleys and is provided with a numberof cups il, which carry the ice cream 42 "from the aperture 36 as it isbeing forced therethrough. Thus it will be seenthat when the shaft 19 is rotated, either by hand or by the motor 21, the plunger will be forced slowly down upon the ice cream which will have only one means of escape, that being up through the hole 36. And as the cream is forced up equal portions will be cut oil and carried up by the cups ail on the elevator to a convenient open place in the casing 3? where the cream will be droppedinto cones or dishes as desired. it is obvious that the portions of cream thus delivered may be increased or decreased in size either by varying the pro portions between the gear radii or by in creasing or decreasing the number oi cups at on the belt 4L0.

' Having now therefore fully shown and described our invention what we claim to be new and desire to protect by Letters ent is:

i. combination with a container, of a plunger adapted to be forced down into-said container, said plunger having an aperture its therein, a frame secured to said container, means in said frame for forcing said plunger slowly down into'said container.

2. In combination with an ice cream container, of a plunger adapted to be forced down into said container, said plunger having an aperture therein up through which ice cream may be pressed, means for automatically delivering equal portions of cream up from said aperture as said plunger is being forced down into said container.

8. In combination with an ice cream container, of a plunger adapted to be forced down into said container, said plunger having an aperture therein up through which ice cream may be pressed, an elevator positioned over said aperture, the same being adapted to deliver said ice cream; up from said aperture.

4. In combination with an ice cream contamer, of a plunger adapted to be forced down into said'container, said plunger having an aperture therein up, through which ice cream may be pressed, an elevator positioned oversaid aperture, the same being adapted to deliver said ice cream up from said aperture, means for simultaneously actuating said plunger and said elevator.

5. In combination with a vertical contalner, of a suitable frame and means for securing: it to the container, a plunger adapted to be forced down into said container, said plunger having a suitable aperture therein to allow the escape of the contents of said container when sald plunger is being forced downtherein, a shaft on said plunger adapted to be guided by said frame.

6. In combination with a vertical con tainer, of a frame and clamping means for securing the same to thecontainer, a plunger adapted-to be guided by saidframe and to be forced down into said container, said plunger having 'a port through which the contents of the container may be delivered when the plunger is being forced down therein.

7.; In combination with a vertical con-.

plunger having a port. through which the contents of the container may be pressed when the plunger is forced down into the container, a motor supported on the plunger and a mechanism whereby the running of said motor will force the the container. I

9. In combination with an ice cream container, of a plunger adapted to be forced down into said container, said plun er having an aperture therein up throu whichice cream may. be pressed, an elevator positioned .over said aperture, the same being adapted to deliver said ice cream up from said aperture, a casing adapted to cover the elevator except for a ward run thereof.

In testimony whereof we afiix our signatures. l
